INVALID-BED.

SPECIFICATIONforming part of Letters Patent N0. 778,570, dated December 27', 1904.

Application filed April 5, 1904. Serial No. 201,624.

To all whom it petty concern/.-

Be it known that we, JAMES A. DEVORE, residing at Pittsburg, and SAMUEL C. YoUN'r, residing at Vilkinsburgjn the county of Allegheny and State of Pennsylvania, citizens of the United States of America, have invented certain new and useful Improvements in Invalid-Beds, of which the following is a specification, reference being had therein to the ac' the invention consists in the novel construe tion, combination, and arrangement of parts to be hereinafter more fully described and claimed.

In describing the invention in detail reference is had to the accompanying drawings, forming a part of this application, and wherein like numerals of reference indicate like parts throughout the several views, in which Figure 1 is a perspective view of our improved bed-bottom. Fig. 2 is a side elevation thereof, showing the same secured upon abedstead. Fig. 3 is a vertical sectional view of the bed-bottom.

In the drawings the reference-numeral 1 represents the ordinary bedstead of the Wellknown construction. Upon this bedstead is placed an invalid-bed bottom, which consists of a rectangular extensible frame 2, carrying corner-posts 3. Aframe 4 has secured thereto the stretcher 5 by laces 6 or other suitable fastening means. This stretcher 5 is preferably formed of waterproof material and a series of openings l t for the purpose of per' mitting an adjustment, and at the end of the connecting-rod 11 is secured a chain or like connection 15, which is adapted to wind over theends of the shaft 16, secured in bearings 17, rigidly attached to two of the cornerposts 3. A like chain Winds upon the opposite end of the shaft 16 in order to operate both sides simultaneously. The end of the shaft carries a crank-lever 18, whereby the shaft may be easily rotated. Upon the shaft 16 isalso secured a ratchet-Wheel 19, which engages the locking-pawl 20, secured upon the frame 2. The mattress is indicated by reference-numeral 21. Set screws or pins 22 are arranged at various points upon the frames 2 and A in order to obtain both a lateral and lineal adjustment of the frames when desired. Like pins 23 are secured in the corner-posts 3, the latter being removed when it is desired to raise or lower the frame 4:, carrying the stretcher 5.

The operation of our improved invalid-bed is as follows: Normally the stretcher 5 will lie flat upon the mattress, and when it is desired to raise the patient the pins are re moved and the crank 18 is operated, thereby straightening the toggle-levers 9 and raising the stretcher a suflicient distance from the mattress to insert a vessel. WVhen it is desired to lower the stretcher, the reverse operation takes place and the patient will be gradually lowered to a position that will permit the patient to again lie upon the mattress.

It will be understood that the locking-pawl 20 will secure the parts in a locked position when the stretcher is in the raised position.

The many advantages obtained by the use of our improved bed will be readily apparent from the foregoing description, taken in connection with the accompanying drawings.

It will be obvious that various slight changes may be made in the details of construction without departing from the general spirit of our invention.

Having fully described our invention, what we claim as new, and desire to secure by Letters Patent, is-

1. In a removable attachment for bedsteads the combination of a lower frame adjustable in length and width and having rigid upwardlyextending corner-posts, with an upper frame adjustable in length and width and having rigid depending corner-posts telescoping in the cornerposts of the lower frame, and means for locking both frames and the cornerposts thereof in adjusted position, a stretcher secured to the upper frame, a shaft journaled to the lower frame, toggle-levers pivotall attached at one end to the lower frame and at the other end to the upper frame, a horizontal rod pivotally attached at the central hinged portions of the toggle-levers to the said toggle-levers, and a flexible connection attached to the end of said horizontal rod and winding around said shaft.

2. In a removable attachn'ient for bedsteads, the combination of a lower frame having rigid upwardly-extending corner-posts, an upper frame having rigid depending corner-posts telescoping in the corner-posts of the lower frame, means for separately locking each of the corner posts in adjusted position, a stretcher secu red to the upper frame two separate pairs of toggle-levers on the frames, each pair having one end pivotally attached to the upper frame and the other end pivotally attached to the lower frame, a rod connecting the two pairs of toggle-levers, a shaft journaled on the frame and a flexible connection attached to said rod and winding around the said shaft.

In testimony whereof we afiix our signatures in the presence of two witnesses.
